目的 :总结激光原位角膜磨镶术 (L aser in situ Keratomileusis,L ASIK)治疗屈光参差后病人的屈光和视力结果 ,评价此疗法的效果、安全性和可预测性。方法 :2 5例屈光参差病人的 40只眼接受了 L ASIK治疗。术前 ,40只术眼的平均球镜和柱镜分别为 - 11.7± 4.78D(- 3.75～ - 2 2 .0 D)和 1.98± 1.48D(0 .0～ 6 .0 D) ,最佳矫正视力为眼前数指到 1.0 (平均 0 .6 ) ,2 5例病人的双眼平均球镜和柱镜之差分别为 7.47± 3.76 D(2 .5～ 16 .5 D)和 1.2 1± 1.44 D(0 .0～ 5 .75 D)。术后随访时间是 1天 ,1周 ,1、 3、6月 ,1、 2、 3年。结果 :术后 ,所有病人的屈光参差都有显著好转 ,双眼的平均球镜和柱镜之差分别下降到 1.49± 1.36 D (0 .0～ 5 .75 D)和 0 .5± 0 .71D(0 .0～ 2 .2 5 D)。术眼的平均球镜和柱镜分别下降到 - 1.2 4± 2 .0 2 D(1.5～ - 11.0 D)和 0 .5 8± 0 .6 2 D(0～ 2 .2 5 D) ,平均最佳矫正视力上升到 0 .9,31只眼 (77.5 % )的最佳矫正视力增加了 1至 7行。 2 2只弱视眼中 ,14眼 (6 3.6 % )的最佳矫正视力可达到 0 .8或 1.0。未发生明显的术中和术后并发症。结论 :L ASIK是一种安全、有效、预测性好的治疗成人屈光参差的手术方法
OBJECTIVE: To summarize the refractive and visual acuity of laser in situ keratomileusis (LASIK) patients after anisometropia correction and to evaluate the efficacy, safety and predictability of this therapy. METHODS: Twenty-five eyes of 25 patients with anisometropia received L ASIK. The mean spherical and cylinder diameters of the 40 eyes were - 11.7 ± 4.78D (-3.75 ~ -2.2 0D) and 1.98 ± 1.48D (0 .0 ~ 6 .0D) respectively, the best The mean corrected visual acuity was 1.0 (mean, 0.6). The mean spherical and lenticular differences in 25 eyes were 7.47 ± 3.76 D (2.5 to 16.5 D) and 1.2 1 ± 1.44 D (0 .0 ~ 5 .75 D). Postoperative follow-up time was 1 day, 1 week, 1, 3, 6 months, 1, 2, 3 years. Results: All patients had a significant improvement in anisometropia postoperatively, and the difference between the average spherical and lenticular angles decreased to 1.49 ± 1.36 D (0 .0 to 5 .75 D) and 0 .5 ± 0 respectively. 71D (0 .0 ~ 2 .2 5 D). The mean spherical and cylinder diameters decreased to -1.2 4 ± 2 .0 2 D (1.5 - 11.0 D) and 0 .5 8 ± 0. 6 2 D (0 - 2 .25 D), respectively The best corrected visual acuity rose to 0.9, and the best corrected visual acuity increased by 1 to 7 lines in 31 eyes (77.5%). Among 2 2 amblyopic eyes, 14 eyes (3.6%) had the best corrected visual acuity of 0.8 or 1.0. No obvious intraoperative and postoperative complications occurred. CONCLUSION: L ASIK is a safe, effective and predictive surgical method for the treatment of anisometropia in adults
